REST Webservice invocation from Java

Hi Guys,
I am developing an application that needs to invoke a REST webservice and submit XML data to it. The server will then process the request XML data, and return a result, etc.
I have never worked with REST and have spent hours researching it on the NET. I have done SOAP calls in the past, but this seems to be eluding me some what.
Does anyone know of any useful links that explains REST implementation, frameworks / jars needed, or possibly even an example or two that shows me how to submit data via REST to a URL (would be first prize :) ).
Any help would be greatly appreciated.
Many thanks
Mark

RESTful webservices invocation from OSB.

Can some one please explain the best way to develop the OSB service to invoke the Restful services.
1. Only proxy service is enough to handle the request, no need of business service?
2. when moving the code from one env to other, we use a business service to update endpoint url which is the common approach we generally follow, to make the osb service loosely coupled. how to use the business service when invoking the restservice? does we have the base uri value in the transport url and will get appended with the relative-uri value which we frame as part of the request in the outbound variable in the proxy settings?
3. when invoking the rest service do we need to append all the request message to the url itself or the request can be passed separately as request body and the main rest uri will have only the key fields as part of the relative-uri?
4. If we receive huge request message does the URL support the entire request?
5. how the response/error will be returned when calling the Restful webservice?
I am assuming this appraoch. Can some one please confirm does this approach works with RESTful service invocation from OSB.
Request processing:
Source System request-> Proxy Service -> Transformation to end system specific -> Business service (with base-uri -> http://mainappl.com/web/cmr/{relative-uri from outbound transport}) -> endsystem
Response processing:
endsystem Response/Error -> Business Service -> Proxy Service -> transformation to source system specific -> source system.
Please advice which is the best approach to follow while invoking the RESTful webservices from OSB.
Thanks..

Hi,
Thanks for the update. Can you please explain the above mentioned approach works or how it should be?
I have one requirement, can some one explain the implementation for this:
I have one element which is of type unbound. I need to map this element to a single enelement value by separating each element value with a ;, before that I need to check wheteher this element(s) are present in the request then need to appened all these element values to a single element and the end of this element need to append default values.
Scenario:
<student>
<name>asd</name>
<address>
<street>street1</street>
<street>street2</street>
<street>street3</street>
||
||
</address>
to be mapped it to:
<student>
<field name="NAME">asd</field>
<field name="ADDRESS">street1;street2;street3;default1;default2;default3</field>
</student>
Here need to check if street names are present in the request xml, if yes ned to assign it to ADDRESS as mentioned above if street names present or not need to append the default values at the end to the ADDRESS field.
Thanks in advance.

ESB Webservice call from Java client

Hi,
i need to call webservice from Java client which inturn will call ESB
I tried creating proxy from the WSDL in jDeveloper and tried setting the following end points
My concrete WSDL path :http://10.237.25.63:8889/esb/wsil/SubroCaseESBSystem/InputRouter?wsdl
My EM -path:"http://10.237.25.63:8889/event/subrotest/SubroInputrouter"
When i call the concreteWSDL im getting
"HTTP transport error: javax.xml.soap.SOAPException: java.security.PrivilegedActionException: javax.xml.soap.SOAPException: Bad response: 405 Method Not Allowed"
If i call the EM pathim getting
"javax.xml.rpc.soap.SOAPFaultException"
Any guess as how i need to call my ESB from client.

Hello Venkat,
- I have created Java Proxy using Jdeveloper for ESB webservice and I usually use http://host:port/event/...?wsdl, and it creates stub which works without any modification. Let me know, may be I can try sending sample project
- I would like to verify if you are having issue with Java client or ESB itself, are you able to execute that ESB process/service from EM test page or from any other BPEL process?

Chintan

OSB WSDL invocation from java /jsp client!

Hi ,
I did a sample work on invoking osb wsdl(based on DB adapter) from a java/jsp application.It worked fine!
Its a simple select query wth parameter that was configured in my DB adapter.
Below are the steps I follow -
a.Created a DB adapter for collective response
b.created BS out of jca
c.Generated PS based on above BS.
d.Performed some xquery tranformation in PS message flow response piepeline.
e.Exported WSDL and tested it in SOAP UI ,getting the transformed response as required.
When we generate Java client out of above WSDL in Eclipse ,it generates client for DB data,transformed data fields are not seen -How to obtain transformed data too through Java client?will this work ?
Is it gud practice to generate java client directly n Eclipse (OEPE) or do we have any other alternative ways to generate Java client out of OSB WSDL?
Please assist.
Thanks,
Ani

Hi Anuj-
My proxy was generated out of business ,i get 2 wsdl like master-child .Master wsdl holds referecnce to child wsdl.I hope wsdl generation is fine.
When i invoke the proxy wsdl url from Java client ,i get below error -

The initial contextfactory used is RMIIntitialContextFactory.
This class is not available in the B2B classpath. So we added the oc4jclient.jar in ../ip/lib and added to classpath by making an entry in opmn.xml.
The OpmnProcess classes present in optic.jar (opmn/lib) does nt have the method getApplist(). So we updated this jar with jdev jar. Now its throwing an java.lang.UnsupportedClassVersionError: EJBHome.

HOW DO I RUN A UNIX BASH SCRIPT FROM JAVA??

HI. Here's a tricky little problem i have. There's a unix bash script that has some commands in it, that manipulate a file. It appends a certain string variable to a file called users. The users file is an ordinary text file.
I know this script to work perfectly, when i invoke it like this directyl from the command line: ./addusers.sh
or even: bash /downloads/selinux/policy/addusers.sh
Now, i have a java program, and its meant to just execute that script. It doesnt throw any Exceptions at runtime. But when i look at the users file, and expect it to have an extra line that was the string variable, the file is UNTOUCHED!
Again, direct command line invocation works, but not from java. Here's what my invocation from java looks like:
Process p = Runtime.getRunTime().exec("bash downloads/selinux/policy/addusers.sh");
The strange thing is, i tried a different bash command. I tried:
Process p = Runtime.getRunTime().exec("mkdir /temporary");
and this worked!
so why not the other one??
I cant figure it out.

You say:
bash /downloads/selinux/policy/addusers.sh
And you say in Java:
Process p = Runtime.getRunTime().exec("bash
downloads/selinux/policy/addusers.sh");
As if a leading / would be missing from the Java
version...nyix says:>
...OK sorry about that. i DO have a / in front of the downloads.... section in the java method. So its:
Process p = Runtime.getRunTime().
exec("bash /downloads/selinux/policy/addusers.sh");
HELP please?

What we are trying is we are invoking webservice by passing SOAP request and we will get soap response back.I understand what you're trying to do, the problem is with tools you're using it will take a while for you do anything a little away from the trivial... Using string concatenation and URL connection and HTTP post to call webservices is like to use a hand drill... It may work well to go through soft wood, but it will take a lot of effort against a concrete wall...
JAX-WS and JAXB and annotations will do everything for you in a couple of lines and IMHO you will take longer to figure out how to do everything by hand than to learn those technologies... they are standard java, no need to add any additional jars...
That's my thought, hope it helps...

How to call webservice from Java application

Hi XI gurus
Pls let me know how to call a webservice from Java application.
I wanted to build synchronous interface from Java Application to SAP using SAP XI
For example, i need to create Material master from Java application and the return message from SAP, should be seen in Java application
Regards
MD

Hi,
If your JAVA Application is Web based application, you can expose it as Webservice.
JAVA People will pick the data from Dbase using their application and will send the data to XI by using our XI Details like Message Interface and Data type structure and all.
So we can Use SOAP Adapter or HTTP in XI..
If you use HTTP for sending the data to XI means there is no need of Adapter also. why because HTTP sits on ABAP Stack and can directly communicate with the XI Integration Server Directly
If you are dealing with the Webservice and SAP Applications means check this

Urgent :: 11g Invoking Composite from Java/From Webservice Proxy

Hi All,
i have a requirement where in need to when ever the exception occurs it invokes custom java and then it invoked a BPEL process to handle the errror.
in 10.1.3.4 i used to Java Api to invoke the BPEL process and it works fine.
1) . now we are migrating to 11g, i know this API wont work with 11g as the server is on weblogic and client librairies may be different for invoking in composite it in 11g. if any body has invoked a composite using java and the using 11g libraries to invoke the composite ? if so can you please post here ?
2). otherway i tried to create a Web Service proxy using Jdeveloper for the composite, when i test it using Jdeveloper it is working fine, but when i place it in the lib directory, im getting a bad response from server 503.
please see logs below for the second approch

Here is sample to invoke a composite from JSP, this should be same from Java Class. Note that the composite should use adf binding and not ws binding.

Calling SAP Webservice from JAVA ME bad response time

Hello together,
I'm calling a SAP RFC as a Webservice from JAVA ME (Netbeans 6.8). The stub classes I've generated with the Sun Wireless Toolkit. The RFC function stores entries in a SAP database table. The call of the websevice with transmitting the data and the database update in SAP works fine, but I got the response message from SAP with a delay of 40 seconds.
Does anyone know why there is so a long delay in the response and how to fix it?

hi,
is this reproducible or was it just the first call to that service?
it usually occurs that once you call a webservice for the first time, some of the programs (be it your application programs or the even the SOAP runtime itself) required have not been compiled until that and so they are compiled during the webservice call.
This leads to slow response times even time-outs. The effect vanishes once all sources are compiled (i.e. depending on the complexity of your calls after one to a few calls to that service).
So, if the slow response times persist, you should turn on debugging in SICF and see where time is spent...
my 2 cents,

Any help will be appreciated

Hi Abinap.
If you are woking with JEE 1.3 or JAX-RPC.
You need to add some libraries to java project.
Go to the tab "Add Libraries" on context menu of the project: Properties --> Java build Path
Select "Add variable" button, after select the SAP_WEBSERVICES_EXT_LIBS_HOME variable and click on "Extend" Button, finally select all the libraries under lib folder, do the same to the SAP_XML_TOOLKIT_LIBS_HOME variable.
Greetings.
